Title: A method and apparatus for charging and closing tubes or similar containers with flat superposed tablets or similar objects
IPC: B65B43/50
Filed: 1964-09-16
Abstract: 1,079,070. Packaging tablets into tubes. K. STERNBERG. Sept. 16, 1964 [Sept. 19, 1963], No. 37918/64. Heading B8C. A column of tablets 5 is pushed into a tube 4 by a plunger 11 which slides in an inclined groove 3 holding the tablets and tube. In the apparatus described the tablets 5 and tube 4 are fed from a magazine 7 into a groove 3 which is inclined at an angle of 10 degrees to the horizontal through the axis 2. The disc is rotated anti-clockwise so that the tube and tablets are inclined still further, causing the tablets to bear against the plunger 11. During this time the plunger 11 which may be cam activated moves to push the tablets into the tube and it may also close the tube with a stopper 6 which is provided between the tablets and the plunger. Alternatively the column 5 and closure 6 may be moved into the tube solely by the centrifugal force, in which case the disc may be rotated in jerks. As the filled tube moves downwards it is removed from the disc, e.g. by a plunger passing through the bottom of the groove. In an alternative embodiment a frustoconical disc rotating about an inclined axis is used in putting the tablets into the tubes, and the horizontal disc rotating about a vertical axis is used for putting the stoppers into the tubes. In this case the filled tubes are transferred from one disc to the other in an upright position.

Title: Improvements in or relating to centrifugal pumps
IPC: B01F25/64
Filed: 1961-10-25
Abstract: 954,392. Mixing appliances. G. C. MITCHELL, and MOLINS MACHINE CO. Ltd. Oct. 12, 1962 [Oct. 25, 1961], No. 38157/61. Heading B1C. [Also in Division F1] A method of delivering from a centrifugal pump a liquid containing solids which are of such a nature as to float on the surface of the liquid comprises the steps of causing the liquid to move in a vortex by imparting at the inlet of the pump a swirling motion additional to that imparted to it by the rotation of the pump impeller, and adding the solids to the centre of the vortex so as to be sucked thereby into the pump in which they form an intimate mixture with the liquid. The inlet 1 of a centrifugal pump is extended to form a conical funnel 3. Liquid under pressure is fed into the funnel from a pipe 11 which is inclined so as to impart a swirling motion to the liquid whereby a vortex 7 is formed. Particles, e.g. of tobacco, fall from a dispenser 8 at a substantially uniform rate into the centre of the vortex 7 which sucks them into the pump. The pump discharges to a reservoir 6. If air is drawn into the pump through the vortex, thereby causing cessation of pumping, the liquid in the pump will rise into the funnel under the influence of the discharge head in the reservoir 6, whereby the air leak is sealed off and the pump is reprimed.

Title: Process for preparing liquid products from coal or coalcontaining materials and for liquefying such materials
IPC: C10G1/00
Filed: 1928-12-31
Abstract: 330,223. Elkington, H. D., (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). Dec. 31, 1928. Hydrogenation, destructive.-Liquid products are obtained from carbonaceous materials by a multi-stage process, the first stage of which consists in rapidly heating the material with hydrogen under pressure to a pre-determined maximum temperature, at which heating is discontinued, so that the mass immediately begins to cool, the vapour products are drawn off and condensed, and the residue is allowed to cool further. In the second and, if desired, succeeding stages, the residue is subjected to more prolonged heating with hydrogen under pressure, the liquid and gaseous products being removed at each stage. The gases produced in the second or succeeding stages may be used as fuel in any stage of the process. Suitable catalysts, if used, are molybdenum and iodine. 200 g. brown coal containing 24.1 per cent organic oxygen are heated for 40 minutes with a molybdenum catalyst to 460‹ C. under a hydrogen pressure of 240 Kg/cm<2>; on cooling to 325‹ C., 15.6 per cent light oil, 4.6 per cent phenols, 12.5 per cent water, and 23.2 per cent gases, mainly carbon dioxide, are produced. The residue is heated from room temperature to 470‹ C. in the presence of hydrogen and a molybdenum catalyst at the same rate as in the first stage, and is maintained for 15 minutes at 480‹ C., thereby producing 12.0 per cent oils, 1.4 per cent phenols, and 4.6 per cent hydrocarbon gases. The residue treated again similarly produces a further 4.4 per cent oils, 0.2 per cent phenols, and 14.4 per cent residue which by vacuum distillation yields 7.3 per cent oils. Specifications 309,859 and 311,759 are referred to.

Title: Improvements in velocity limiters
IPC: G21C7/16
Filed: 1966-08-30
Abstract: 1,090,198. Reactor control rods. GENERAL ELECTRIC CO. Aug. 30, 1966 [Oct. 23, 1965 (2)], No. 38616/66. Heading G6C. The vertical control rods of a boiling water nuclear reactor are adjusted from beneath the core. To prevent a rapid increase in reactivity upon a control rod moving downwards out of the reactor due to failure of a control rod drive mechanism, the downward speed of the rod is restricted by damping. The restriction is effected by limiting the flow of the coolant past a piston mounted on the rod. The control rod piston moves vertically within a cylinder and has either spring-loaded valves or hinged flaps which are opened by the coolant flow when the rod moves upwards into the reactor, but which are closed when the rod moves downwards.

Title: Improvements relating to data sorting apparatus
Inventor: FROGGATT ROBERT JUSTIN
IPC: G06F7/24
Filed: 1956-12-19
Abstract: 875,064. Sorting digital data words. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 19, 1957 [Dec. 19, 1956], No. 38624/56. Class 106 (1). Binary digit words recorded in random order on a magnetic drum 1 are transferred to and arranged in numerical order of reference numbers prefixing each word in a matrix store 13. Initially the store 13 is filled with dummy words consisting entirely of binary 1's. A word read from the drum 1 is transferred, step by step, to a shifting register 8 while a word from the lowest order position in the matrix 13 is transferred similarly to a shifting register 18. During the transfers corresponding digits of the reference numbers, in descending order, are compared by cross-coupled gates 21, 22 arranged so that no change occurs in the state of triggers 19 and 20 as long as the digits agree but, on a disagreement, trigger 20 is changed over if the digit from the "A word" is a zero and the digit from the "B word" is a one, and trigger 19 is operated if the opposite conditions occur. After such an action inhibit gates 23 and 24 prevent any further change of triggers 19 and 20 until the end of the word is reached. If the reference number of the A word proves to have the lesser value the actuation of trigger 20 causes the word to be routed via a gate 26 to that line of the matrix store 13 from which the B word was taken, while the B word is transferred to the store 8 via gates 28 and 32 subsequently to be compared with a word from the next line of the matrix store. Since, however, this word is bound to be of higher value, the above process will be repeated so that all the significant contents of the matrix store will be shifted by one row to make room for the newly inserted word. This action is terminated when dummy words from the matrix store are detected by an " all ones " detector 34. If, on the other hand, the comparison shows that the word read from the drum 1 is the greater, the actuation of the trigger 19 causes this word to circulate via register 8 and gates 25 and 32 while the B word is returned under control of a column shift register 29, to that row of the matrix store 13 marked by a distributer 16. The register 29, on completing a cycle, shifts the row distributer 16 by one step. The word from the next row of the matrix store is then compared with the A word and so on until the correct position for the latter is found in the store 13. The operations will then be as described above for a lesser-valued A word.

Abstract: 849,824. Hand knitting machines. SCHUMM, E. Dec. 21, 1956 [Dec. 23, 1955; June 26, 1956], No. 38968/56. Class 74 (2). A device for altering the positions of selected needles of a manually-operated machine, between successive operations of the cam carriage, comprises a block 1 on the underside of which are intersecting guide grooves 20, 21, for the needle feet, both inclined to a rail 11 by which the device may be guided along one of the earn carriage guiding-rails, and a spring-urged wire flap or flaps 7 by contact between which and the needle feet, one guide groove is opened and the other blocked while the needle feet concerned pass. Thus, with the arrangement of Fig. 2, traverse of the device in the direction of the arrow X will cause needles in the knitting position A1 to be transferred to a position A2 and vice versa. The device may be equipped with a design wheel having teeth, such as 26, 27, 28, 29, engaging different numbers of needle feet. A tooth 26 will not alter the eventual position of the needle feet, whereas other teeth will cause change from position A1 to position A2. The paths of needle feet through the device are indicated in Fig. 4. In another form, Fig. 10, there is provided a block 45 capable of being pivoted through 45 degrees and which, when moved in the direction of the arrow S, causes exchange of needle foot position as indicated on the Figure, but which, when moved in the opposite direction, produces no functional displacement of the needles; such a device may be secured to the cam carriage. The block may be replaced by a design wheel consisting of a disc with differentlyshaped teeth and a pinion having teeth all of the same shape.

Title: Improvements relating to the finishing of parts
Inventor: BUFFIN ARTHUR WILLIAM JAMES
IPC: B24B31/00
Filed: 1962-12-20
Abstract: 1,066,714. Finishing. ROTO-FINISH Ltd. Dec. 20, 1963 [Oct. 16, 1962], No. 39098/62. Heading B3D. A workpiece, e.g. of steel, such as a helically toothed gear, is finished, i.e. deburred, ground or polished, by burying the workpiece in a mass of loose solid chips or particles of abrasive material flooded with liquid and rotating the workpiece, while it is buried, at a speed of at least 500 r.p.m., first in one direction and then in the other. An electric motor 10 drives, through a chain, a spindle 11 at a speed of at least 500 r.p.m., the preferred range being 500-1000 r.p.m. although speeds up to 1500 r.p.m. may be employed. The motor speed may be fixed, variable in steps or infinitely variable. The spindle 11 has a collet for enabling a workpiece W to be removably secured to the spindle for rotation therewith, the collet being operable by a pusher rod 13 connected to a lever 14 rocked by a pneumatic jack 16 controlled by a foot operated valve. A sub-frame 21 movable vertically relative to the main frame by a pneumatic jack 22 carries a tub 20 containing a mass of abrasive material. Also mounted on the sub-frame 21 are a tank 23 and a motor driven pump 24, the latter pumping liquid from the tank through a hose 26 into the tub. The liquid is drained off from the bottom of the tub and passed through a filter, the cleaned liquid being returned to the tank. With the sub-frame 21 in its bottom position, a workpiece W is fixed in the collet. The pump 24 is set in operation, and two timers associated with the motor 10 are set manually to equal or unequal periods. Subject to the closure of doors 33, motor 10 is started. Operation of the motor starter initiates operation of the pneumatic jack 22 to raise the sub-frame. When it reaches its top position the sub-frame 21 actuates a limit switch to set the first timer in operation; when this times-out an electrical signal reverses the motor 10 and sets the second timer in operation; when this times-out an electrical signal stops the motor 10 and returns the sub-frame to its bottom position. The apparatus described may be used to put a small radius on the crowns of the gear teeth of a hardened crown wheel for a motor car and remove hardening scale. Small partially rounded rock chips are then used. A fine abrasive is used for polishing. The pneumatic jack 22 may reciprocate the sub-frame 21 automatically throughout the cycle, reversing valves or limit switches being associated with the jack. The tub 20 may be rotated about an axis parallel to, but off-set from, the axis of rotation of the spindle 11.
